Receptor Information WR performed a receptor survey update at the site on April 15, 2015, which included identification  of supply wells located within 1,000 feet of the release area as well as research into the availability  of  municipal  or  county  water  supplies.   Potable  water  is  provided  to  the  site  and  surrounding  properties exclusively through private supply wells, and no public water supply is available to the  site or surrounding properties through municipal or county facilities.  WR identified seven supply  wells located within a 500‐foot radius of the site.  Of these wells, two (WSW‐4 and WSW‐9) are  currently  inactive.   Supply  well  WSW‐1  was  reported  by  previous  consultants  to  have  been  abandoned; however, the current property owner (Mr. Roy Elks) stated to WR personnel that the  well  had  never,  to  his  knowledge,  existed.   An  additional  twelve  supply  wells  were  identified  between 500 and 1,000 feet of the source location on the site.  Of these wells, eleven are believed  to be active potable supply wells, and the remaining well (WSW‐17A) is reported by the property  owner to be a “dry” well.    Supply  wells  WSW‐10  and  WSW‐13,  formerly  having  been  identified  as  being  located  within  1,000 feet of the release area, were found to actually be located greater than 1,000 feet from the  source  location.   Previous  consultants  had  based  their  search  radius  on  the  center  of  the  site  property,  rather  than  the  center  of  the  suspected  source  area,  which  would  have  these  wells  located within the 1,000‐foot radius.  As many as twenty‐two additional supply wells (including  WSW‐10 and WSW‐13) are located within 1,000 and 1,500 feet of the source area.  WR oversaw  the  installation  of  a  replacement  well  for  WSW‐3  during  September  2020.   Following  the  replacement well installation (WSW‐3A), WR oversaw the abandonment of WSW‐3 on February  3, 2021.  A point of entry (POE) system had been installed on supply well WSW‐4, but the POE  system on the well was reportedly disconnected by the owner several years ago. Research of the  site and vicinity through the NC Source Water Assessment Program (SWAP) indicates that the site  does not lie within a Wellhead Protection Area, and the site is not located within the Coastal Plain  Physiographic Province of North Carolina.    Analytical results for supply well samples obtained from WSW‐2, WSW‐6 and WSW‐8 in June  2023 did not show the presence of targeted compounds at levels above the MDLs for SM6200B  or EPA‐504.1.  Data for the sample collected from WSW‐3A and WSW‐4 showed 1,2‐DCE and  EDB present at concentrations exceeding the 2L Standard but beneath the US EPA Maximum  Contaminant  Level  (MCL)  for  the  compounds.   WR  does  not  believe  the  presence  of  these  chemicals in WSW‐3A and WSW‐4 to relate to the petroleum release at the Former Sam Puckett  Property, as these compounds have not historically been detected in monitoring wells MW‐2,  MW‐2D, MW‐3R MW‐4, MW‐4D, MW‐5 or MW‐9, each located between the source location  and the supply wells.    4. Remediation Activities Two USTs were removed from the location on December 16, 2019, included one 1,000‐gallon  UST and one 500‐gallon UST, both assumed to have been used for the storage of petroleum fuels.   No remedial actions beyond UST closures have been completed at the location, to date.    WithersRavenel Our People. Your Success.    Former Sam Puckett Property WR Project # 23‐0307‐CY  Monitoring Report August 2023  5      5. Recommendations    Based on the results of assessment and monitoring activities conducted at the site in association  with this TA and what appears as a decreasing trend in contaminants in MW‐1, WR recommends  the following:     Continued performance of routine groundwater and supply well monitoring at the site.   If adequate funding is available based on site risk, consider injection of chemical amendment  such as persulfate or BOS200 activated carbon to reduce contaminant concentrations in  groundwater.           WithersRavenel Our People. Your Success.    Former Sam Puckett Property WR Project # 23‐0307‐CY  Monitoring Report August 2023  6    SECTION C.  SITE HISTORY AND CHARACTERIZATION    WR has completed a groundwater monitoring well and supply well sampling event for the  referenced site in association with TA‐01 at the facility.  The following information summarizes  the site history and characterization.      1. UST Information    1.1 Former USTs  The UST systems removed from the location on December 16, 2019, included one 1,000‐gallon  UST and one 500‐gallon UST, both assumed to have been used for the storage of petroleum fuels.   These tanks were wholly or in part located within the northern margin of the R/W of NC Highway  39.  No information relating to the last uses of the tanks is available. The UST systems were orphan  tanks situated on property formerly owned by Mr. Sam Puckett, who obtained ownership of the  property in October 1992 and never operated the UST systems.  The tanks were reportedly in  place when the property was owned by Mr. Wallace A. Duke (deceased) & Ms. Dorothy P. Duke,  pre‐dating Mr. Puckett’s ownership in 1992.  Table B‐1 summarizes known information regarding  the former UST systems.    The location of the site imposed on the USGS Topographic Map for the vicinity is included as  Figure 1, while site improvements, including former USTs and monitoring well locations are  depicted on Figure 2.      2.       Description of Release/General Assessment History    The following summary of the assessment history is based on WR’s review of historical files for  the subject incident:  Based on an internal memorandum at the North Carolina Department of Environmental Quality or  “NCDEQ” [formerly the Department of Environment and Natural Resources (NCDENR)] in  association with an application for State Lead Site acceptance, residents at the nearby Stephens  Rental Property (Incident# 9174) complained about the quality of water from an on‐site water  supply well. The groundwater monitoring wells at the site are apparently associated with the  Stephen’s Rental Property Site (TF‐9174). The Stephens Rental Property is located at 8105 NC  Highway 39 South, adjacent to the Sam Puckett Property site. The following summary of the  assessment history is based on WR’s review of historical files for the subject incident:      Stephens Rental Property (Incident # TF‐9174)      According to an Underground Storage Tank Closure Report prepared by ATEC Associates and  dated December 1, 1994, one 250‐gallon heating oil UST was removed from the Stephens  Rental Property on October 19, 1994. Free product was reportedly observed in the soils  immediately below the former UST. Approximately 25 tons of petroleum contaminated soils  were excavated and removed from the UST excavation. The laboratory analytical results for  confirmatory soil samples collected at the time of UST closure indicated that total petroleum  hydrocarbons (TPH) diesel range organics (DRO) were detected in concentrations between  WithersRavenel Our People. Your Success.    Former Sam Puckett Property WR Project # 23‐0307‐CY  Monitoring Report August 2023  7    2,880 parts per million (ppm) and 23,400 ppm. Groundwater was reportedly not encountered  during the UST excavation.   In addition to removing the UST, ATEC also collected water samples from three nearby water  supply wells (two wells at the Puckett Residence, and one at the Fire Station). The laboratory  analytical results for these samples indicated that no petroleum‐related constituents were  detected above the laboratory MDLs. ATEC also sampled the well associated with the  Stephens Rental Property, which was equipped with a carbon adsorption system. Water  samples were collected from both influent and effluent sides of the system. The laboratory  analytical results for the water samples indicated that several VOCs were detected in  concentrations below the 2L Standards in the water entering the treatment system, and no  VOCs were detected in the effluent sample from the system   According to the Report of Environmental Services prepared by Mid‐Atlantic Associates and  dated December 3, 1996, groundwater monitoring wells MW‐1 through MW‐3 were installed  in October 1996. Monitoring well MW‐1 was installed on the property at 10 Puckett Trail to  the northwest and MW‐2 was installed at 20 Puckett Trail to the northwest of the site.  Monitoring well MW‐3 was installed at the site near the former UST excavation.   According to the Groundwater Monitoring Event Report prepared by Schnabel Engineering and  dated June 24, 2003, monitoring wells MW‐1 through MW‐3 were sampled on May 14, 2003.  The laboratory analytical results for the groundwater samples indicated that several VOCs  were detected in concentrations exceeding their respective 2L Standards at location MW‐1.  In addition, four soil borings were advanced near the former UST excavation on the Stephens  Rental Property. The laboratory analytical results for the soil samples indicated that no  petroleum‐related constituents were detected at concentrations above the MDLs.    Sam Puckett Property (Incident # TF‐26305)      In July 2003, Mr. Sam Puckett, who is the owner of the Sam Puckett Property at 10 Puckett  Trail, received a Notice of Regulatory Requirements (NORR) from the NCDENR due to the  detections of VOCs exceeding 2L Standards in monitoring well MW‐1, which was installed on  his property in association with the Stephens Rental site.  In an Affidavit signed by Mr. Puckett  on January 20, 2004, Mr. Puckett indicated that he purchased the property in 1992 and did  not operate or even know about any USTs associated with the property. The remains of an old  service station are located on his property.   According to a Monitor Well Installation and Water Supply Well and Groundwater Sampling Report  prepared by Schnabel Engineering, eight soil borings were installed to depths of between 7  and 19 feet below ground surface at locations on the Sam Puckett Property and on adjacent  parcels. Soil samples collected from the soil borings were screened in the field for the presence  of VOCs. The soil borings that exhibited the highest VOC measurements (SB‐1 through SB‐3,  and SB‐8) were subsequently converted into monitoring wells (MW‐4 through MW‐7). Soil  samples from the borings were reportedly not collected for laboratory analysis. The entire  monitoring well network (MW‐1, MW‐2, and MW‐4 through MW‐7) was sampled on March  9, 2004. Monitoring well MW‐3 was not located during that sampling event. The laboratory  analytical results for the groundwater samples indicated that VOCs were detected in  concentrations exceeding their respective 2L Standards in the samples from monitoring wells  MW‐1 and MW‐6. The concentration of benzene exceeded the 2L Standard in the sample  monitoring well MW‐7. In addition, water samples were collected from water supply wells  WithersRavenel Our People. Your Success.    Former Sam Puckett Property WR Project # 23‐0307‐CY  Monitoring Report August 2023  8    WSW‐1 through WSW‐6. The laboratory analytical results for the water supply well samples  indicated that 1,2‐dichloroethane was detected in concentrations exceeding the 2L Standard  in the samples from WSW‐3 and WSW‐4, and the benzene concentration in the sample from  WSW‐3 exceeded the 2L Standard.    The groundwater monitoring network (MW‐1, MW‐2, and MW‐3 through MW‐7) was  sampled sporadically between March 2004 and October 2012. Monitoring well MW‐3 had not  been located since prior to March 2004. The laboratory analytical results for groundwater  samples collected during this period indicated several VOCs present in the samples from MW‐ 1 and MW‐6 in concentrations exceeding their respective 2L Standards. In addition, water  supply wells WSW‐1 through WSW‐6 were also sampled sporadically between March 2004  and May 2008. Water supply wells WSW‐3 and WSW‐4 reportedly have POE systems  connected to the wells. The laboratory results for the water supply well samples indicated the  presence of several VOCs in the influent samples for the POE systems installed on WSW‐3  and WSW‐4. The effluent samples from the POE systems did not have any detections of  petroleum‐related constituents exceeding the MDLs.  In addition, no petroleum‐related  constituents were detected in the other water supply wells sampled.   A receptor survey was completed by Crawford Environmental Services as part of a  groundwater monitoring event in December 2012. According to the receptor survey, municipal  water is not available to the area. Nineteen water supply wells were identified within 1,000  feet of the site (WSW‐1 through WSW‐19). Water supply well WSW‐1 has been abandoned,  and supply wells WSW‐2 and WSW‐9 are both inactive wells. The remaining sixteen wells are  actively used as sources for drinking water and other domestic uses.   WR conducted a groundwater and supply well sampling event during June 2014.  Analytical  results for groundwater samples were consistent with previous sampling events, and generally  showed a decreasing trend of compounds in affected wells.  Several compounds were reported  at locations MW‐1 and MW‐6 at levels above their respective 2L Standards, and EDB was  reported in the sample from MW‐6 at a level exceeding the Gross Contaminant Level (GCL) for  the compound.  Results of a GPR survey on the site identified the potential presence of two  previously unidentified USTs beneath the property.  WR advanced four hand augured soil  borings over the location of one of the potential USTs, and encountered refusal at a depth of  approximately 22 inches in each boring at the location of a solid metal obstruction.   WR performed a receptor survey update, supervised performance of a GPR survey and air  knifed soil boring installations, gauged, purged and sampled site monitoring wells and purged  and sampled WSW‐2, WSW‐3 (Pre‐ and Post‐POE) and WSW‐8.  Results of the receptor  survey verified a lack of available potable water from a private or municipal service, and  confirmed the presence of six active and one inactive (WSW‐9) supply wells within 500 feet  of the source area on the site, and an additional twelve active supply wells between 500 and  1,000 feet of the source area.  Results of a GPR survey and subsequent air‐knifed soil borings  confirmed the presence of two steel USTs, located within the NCDOT R/W of NC Highway  39, approximately 10 feet northwest of monitoring well MW‐1.  Analytical results for soil  samples retrieved from borings SB‐1 through SB‐4, indicated the presence of one or more  compounds in each of the samples at levels exceeding their respective Soil to Water MSCCs.   Aliphatic and aromatic hydrocarbons were reported in samples obtained from borings SB‐3  and SB‐4 at levels exceeding their respective Residential MSCCs.   Based on the analytical  results for these four samples, the lateral extent of soil contamination surrounding these USTs  has not been defined to levels equivalent to the Soil to Water MSCCs.    WithersRavenel Our People. Your Success.    Former Sam Puckett Property WR Project # 23‐0307‐CY  Monitoring Report August 2023

obtained from monitoring wells MW‐1 and MW‐6.  In addition, 1,2‐dibromoethane (EDB) was  reported in the sample from MW‐6 at a level exceeding the GCL for the compound.  Analytical  results for groundwater samples retrieved from wells MW‐2, MW‐4, MW‐5 and MW‐7 did  not indicate detectable concentrations of any petroleum‐related compounds by SM6200B or  EPA‐504.1 (EDB).  Analytical results for supply well samples obtained on April 15, 2015  indicated the presence of EDB in the samples from WSW‐2, WSW‐3 (Pre‐POE), WSW‐3 (Post‐ POE) and WSW‐8.  Levels of the compound reported in WSW‐3 (Pre‐POE) and WSW‐3 (Post‐ POE) were in excess of the 2L Standard for EDB. 1,2‐Dichloroethane was also detected in the  sample from WSW‐3 (Pre‐POE) at a level exceeding the 2L Standard for the compound.   In association with TA‐04 for the site under a previous contract, WR attempted to obtain an  access agreement for the Donald Wilby property to allow for the installation of additional  monitoring wells on his property and submitted a R/W Encroachment agreement to the NC  DOT to permit the installation of monitoring wells and removal of the USTs in the RW of NC  Highway 39.  WR was further tasked with evaluating water supply wells located downgradient  of the site source area, to include wells WSW‐1, WSW‐2, WSW‐3, WSW‐4, WSW‐8 and  WSW‐9.    Although WR submitted an access agreement to Mr. Wilby through Certified US  Mail, no response to the request for access has been received, to date.  Following review,  NCDOT issued encroachment contract E53‐35‐15‐026 on July 28, 2015.  This encroachment  includes provisions for installing two monitoring wells in the RW as well as the excavation and  removal of the USTs adjacent to MW‐1.  WR was unable to locate supply well WSW‐1, which  was abandoned according to the Schnabel Engineering Monitoring Well Installation and Water  Supply Well and Groundwater Sampling Report dated April 2004.  Despite having attempted to  contact the owner of WSW‐4 both through phone calls and a visit by WR personnel to the  location, WR was unable to gain access and obtain complete information about the  construction of WSW‐4.  WR completed additional inquiry into the water supply well by  phoning the Franklin County Health Department‐Division of Environmental Health, who  informed WR that no records of wells, or well construction records, are available prior to 2008.   Supply wells WSW‐3 and WSW‐9 were found to have shallow screens, which likely intercept  shallow groundwater of the surficial aquifer.     In July 2016, WR gauged, purged and sampled monitoring wells MW‐1, MW‐2, and MW‐4  through MW‐7, and purged and sampled supply wells WSW‐2, WSW‐3 (Pre‐ and Post‐POE),  WSW‐6 and WSW‐8. Analytical results for groundwater samples obtained from site  monitoring wells on July 21, 2016 indicated one or more petroleum‐related compounds in  samples obtained from wells MW‐1 and MW‐6.  Several compounds detected in each of the  samples were reported at concentrations exceeding their respective 2L Standards.  EDB was  reported in the samples from MW‐1 and MW‐6 at levels above the 2L standard for the  compound.  The concentration of EDB in MW‐6 was in excess of the GCL for the compound.   Analytical results for samples from the remaining wells did not indicate the presence of  compounds at concentrations exceeding the MDLs for SM6200B or EPA‐504.1.  Analytical  results for the samples obtained from water supply wells on July 21, 2016 indicated the

In August 2017, WR supervised the installation of three Type II, 2‐inch diameter monitoring  wells (MW‐3R, MW‐8 and MW‐9), two additional “deep profile” Type II, 2‐inch diameter  monitoring wells (MW‐2D and MW‐4D), gauged, purged and sampled monitoring wells MW‐ 1 through MW‐9, and purged and sampled supply wells WSW‐2, WSW‐3 (Pre‐ and Post‐POE),  WSW‐4, WSW‐6 and WSW‐8.  Analytical results for groundwater samples obtained from site  monitoring wells on August 9, 2017 indicated the presence of one or more petroleum‐related  compounds in the samples obtained from MW‐1 and MW‐2D.  One or more compounds in  the sample from MW‐1 were reported at concentrations in excess of their respective 2L  Standards.   Historical data has shown the greatest levels of contaminants in samples  originating from MW‐6; however, this well could not be sampled during August 2017 as it was  “dry”. Analytical results for samples obtained from monitoring wells MW‐2, MW‐4, MW‐4D,  MW‐5, MW‐7, MW‐8 and MW‐9 did not show the presence of VOCs at levels exceeding the  laboratory MDL for SM6200B.  Analytical results for supply well samples obtained from WSW‐ 2, WSW‐6 and WSW‐8 did not show the presence of petroleum‐related compounds according  to SM6200B.  Analytical results for the Pre‐POE sample from WSW‐3 showed EDB present  at a concentration exceeding the 2L Standard and US EPA MCL for the compound.  Data for  this sample also showed t‐amyl alcohol (TAA) at an estimated concentration of 5.33 µg/L.  WR  believes the reported presence of this compound to be suspect, and likely an artifact relating  to elevated reported detection limits for the sample.  The two samples in which TAA was  reported, MW‐1 and WSW‐3 (pre‐POE), were also the only two wells in which benzene was  reported, both having elevated laboratory reported detection limits.  Analytical results for the  Post‐POE sample for the well did not show any petroleum‐related compounds present above  the laboratory MDL.  Results for the sample obtained from WSW‐4 showed EDB present at a  concentration above both the 2L Standard and US EPA MCL for the compound.     During November 2018, WR obtained a supply well sample from WSW‐3 in conjunction with  ProAct‐Carbonair’s scheduled POE system maintenance at the location.  This sample was  collected to verify results for samples obtained from the well by WR and ProAct‐Carbonair.   Data for the sample showed concentrations of benzene and EDB in excess of their respective  2L Standards, while the level of EDB also exceeded the US EPA MCL for the compound.     Analytical results for groundwater samples obtained from site monitoring wells on January 17,  2019 indicated one or more petroleum‐related compounds in samples obtained from wells  MW‐1 and MW‐6.  Several compounds detected in these samples were reported at  concentrations exceeding their respective 2L Standards.  Analytical results for samples from  the remaining wells did not indicate the presence of compounds at concentrations exceeding  the MDLs for SM6200B or EPA‐504.1.  Analytical results for the samples obtained from water  supply wells on January 17, 2019 indicated the presence of EDB in WSW‐3 (Pre‐POE) at a  concentration in excess of the 2L Standard and the US EPA MCL for drinking water.  Results  for the Post‐POE sample from WSW‐3 showed the continued presence of EDB at a level above  the 2L Standard for the compound (but below the US EPA MCL).     WR completed the closure of two UST systems at the location during December 2019.  The  UST systems removed from the location included one 1,000‐gallon UST and one 500‐gallon  UST, both assumed to have been used for the storage of petroleum fuels.  Based upon the  concentrations of TPH as GRO and DRO detected in each of the soil samples obtained during  completion of closure activities, a release was verified in association with the UST systems.

3.  Brief Description of Site Characteristics    The property is located in Epsom, Franklin County, North Carolina (Figure 1).  The facility address  is 10 Puckett Trail, and the location is currently vacant (Figure 2).  The Franklin County Parcel ID  No. for the property is 036554.  A one‐story building, which was reportedly a former gas  station/convenience store was located near the southwestern corner of the property.  The  structure was razed sometime between May 2012 and April 2015.  A single‐story residential home  is located to the northeast of the former structure on the parcel.  This residence is serviced by  supply well WSW‐8.  Two USTs were located within the NCDOT R/W of NC Highway 39, near  the southwestern wall of the former structure location.  These tanks were permanently closed in  December 2019.  Surface cover at the former UST locations include scattered areas of asphalt,  while surface cover on remaining portions of the site include grass and/or gravel.      4.       Information on Receptors/Potential Receptors    WR performed a receptor survey update at the site on April 15, 2015, which included identification  of supply wells located within 1,000 feet of the release area as well as research into the availability  of municipal or county water supplies.  Results of the update include the following:     Potable water is provided to the site and surrounding properties exclusively through private  supply wells.   No publicly available water supply is available to the site or surrounding properties through  municipal or county facilities.   WR identified seven supply wells located within a 500‐foot radius of the site.  Of these wells,  two (WSW‐4 and WSW‐9) are currently inactive.  Supply well WSW‐1 was reported by  previous consultants to have been abandoned; however, the current property owner Mr. Roy  Elks stated to WR personnel that the well had never, to his knowledge, existed.  An additional  twelve supply wells were identified between 500 and 1,000 feet of the source location on the  site.  Of these wells, eleven are believed to be active potable supply wells, and the remaining  well (WSW‐17A) is reported by the property owner to be a “dry” well.   Supply wells WSW‐10 and WSW‐13, formerly having been identified as being located within  1,000 feet of the release area, were found to actually be located greater than 1,000 feet from  the source location.  Previous consultants had based their search radius on the center of the  site property, rather than the center of the suspected source area, which would have these  wells located within the 1,000‐foot radius.   As many as twenty‐two additional supply wells (including WSW‐10 and WSW‐13) are located  within 1,000 and 1,500 feet of the source area.  WithersRavenel Our People. Your Success.

SECTION D.  MONITORING WELL SAMPLING –JUNE 2023    WR conducted a site‐wide groundwater monitoring event at the in association with TA‐01 under  NCDEQ Contract #N70522‐C.  While tasked with collection of groundwater samples from  monitoring wells MW‐2, however, WR personnel were unable to locate the well.  Therefore, MW‐ 2 was not sampled.  Monitoring well MW‐6 has been destroyed, and was, therefore, not sampled.   WR also purged and sampled supply wells WSW‐2, WSW‐3A, WSW‐4, WSW‐6 and WSW‐8 in  association with this TA.    These activities are described below.    WR mobilized to the site on June 8, 2023 for the purposes of completing a site‐wide groundwater  sampling event.  WR personnel were unable locate MW‐1 on June 8, 2023 and returned to the  location on June 29, 2023 to locate and sample the well.      1 Groundwater Elevations    Prior to the purging and sampling of site monitoring wells, WR personnel opened and gauged each  well with an electronic water level indicator to determine the depth to groundwater.  In the  performance of these activities and eventual purging of the wells, free product was not measured  in any of the monitoring wells on the site.  The depth to groundwater measurements as recorded  in the monitoring wells on June 8, 2023 ranged from 8.12 feet below the top of well casing (ft‐ BTOC) in monitoring well MW‐3R to 14.69‐ft‐BTOC in monitoring well MW‐8  Based on  groundwater elevation measurements obtained on June 8, 2023 groundwater averaged 2.1‐ft  shallower than those measured in June 2022.  Based on groundwater elevation measurements  obtained in June 2023, groundwater flow currently appears to flow divergently to the southeast  and northeast as shown on Figure 3.  As depicted on Figure 3, gradient at the location may be  affected by the removal of the USTs in December 2019 and emplacement of non‐native fill  materials in the excavated area.  Groundwater elevation measurements for this event are  presented in Table B‐7.  Historical groundwater elevations are included in Table B‐9.    2 Groundwater Sampling and Analytical Results    Monitoring Well Sampling     WR personnel obtained groundwater samples from MW‐1, MW‐2D, MW‐4, MW‐4D, MW‐5,  MW‐7, MW‐8 and MW‐9 following gauging and purging.  As previously stated, MW‐1 could not  be located on June 8, 2023 but was later found and sampled on June 29, 2023.  Each well was  purged and sampled with a separate polyethylene bailer, as described in the procedures outlined  in Appendix C.  After completion of an appropriate purge, groundwater samples were obtained  with the bailer(s) and decanted directly into laboratory prepared sample containers holding  appropriate preservative(s) as required.  Groundwater samples were submitted to Waypoint  Analytical, LLC (Waypoint) for analysis by SM6200B and EPA‐504.1 (EDB).  Field notes associated  with the performance of assessment activities at the site are included in Appendix B.       WithersRavenel Our People. Your Success.  Former Sam Puckett Property WR Project # 23‐0307‐CY

2023 analyzed by SM6200B indicated several petroleum‐related compounds in samples obtained  from well MW‐1.  Naphthalene was reported in the sample at a concentration exceeding the 2L  Standard.  Results for the remaining wells did not show the presence of targeted compounds at  levels exceeding the laboratory MDL.    EPA‐504.1 (EDB)  Analytical results for groundwater samples obtained from site monitoring wells on June 8, 2023  analyzed by EPA Method 504.1 did not show the presence of EDB in any samples submitted for  analysis.     Groundwater analytical results are summarized in Table B‐4 and shown on Figure 4.  The  laboratory analytical report and chain‐of‐custody record associated with groundwater samples  obtained from site monitoring wells during June 2023 are included in Appendix A.     Based solely on total BTEX concentrations for June 2023 compared to those from June 2022,  groundwater analytical results for samples showed a 48.5% decrease in MW‐1.   WR believes  these continued reductions in groundwater contaminants within the well to relate to the removal  of the USTs from the location in December 2019, which included the removal of a small volume  of saturated source area soils.  WR believes that the removal of severely contaminated soils and  emplacement of fill material has essentially created a more permeable pathway for groundwater  flow towards MW‐1, allowing for “washing” of contaminants through vadose zone soils.  In  addition, based on groundwater elevation measurements obtained on June 8, 2023 groundwater  averaged 2.1‐ft shallower than those measured in June 2022.    The extent of surficial groundwater contamination has been nearly defined, with minor data gaps  to the west and southeast of the source area.  No assessment of water quality conditions with the  underlying bedrock aquifer has been performed at the site to date; however, analytical data for  “deep” Type II wells MW‐2D and MW‐4D did not show impact by petroleum compounds, with  the exception of 1,2,4‐trimethylbenzene (reported in the sample obtained from MW‐2D in August  2017 at a concentration beneath the 2L Standard), inferring that contaminants do not appear to  be migrating to deeper water‐bearing zones to the northeast of the source area (towards WSW‐ 8).  WithersRavenel Our People. Your Success.  Former Sam Puckett Property WR Project # 23‐0307‐CY

SECTION F.  CONCLUSIONS AND RECOMMENDATIONS  This report documents the results of field activities conducted at the site for TA‐01, which included  the gauging, purging and sampling of monitoring wells MW‐1, MW‐2D, MW‐3R, MW‐4, MW‐4D,  MW‐5, MW‐5D, MW‐7, MW‐8 and MW‐9, and collection of supply well samples from WSW‐2,  WSW‐3A, WSW‐4, WSW‐6 and WSW‐8.  Conclusions based on observations, analytical results  and research relating to the release at the site combined with historical information include the  following:  Seven supply wells are located within 500‐ft of the site.  Of these wells, five are active and two are inactive: An additional twelve supply wells were identified between 500 and 1,000 feet of the source location on the site.  Of these wells, eleven are believed to be active potable supply wells, and the remaining well (WSW‐17A) is reported by the property owner to be a dry well. Two USTs were removed from the NCDOT R/W adjacent to the southwestern boundary of the site in December 2019. Analytical results for groundwater samples obtained from the site monitoring wells indicated the presence of several petroleum‐related compounds in the samples from MW‐1. Naphthalene was reported in the sample from MW‐1 at a concentration exceeding the 2L Standard. Based solely on total BTEX concentrations for June 2023 compared to those from June 2022, groundwater analytical results for samples showed a decrease of 48.5% in MW‐1.  WR believes these continued reductions in groundwater contaminants within the well to relate to the removal of the USTs from the location in December 2019, which included the removal of a small volume of saturated source area soils.  WR believes that the removal of severely contaminated soils and emplacement of fill material has essentially created a more permeable pathway for groundwater flow towards MW‐1, allowing for “washing” of contaminants through vadose zone soils.  In addition, based on groundwater elevation measurements obtained on June 8, 2023, groundwater averaged 2.1‐ft shallower than those measured on June 1, 2022. Analytical results for groundwater samples obtained from the remaining monitoring wells in June 2023 did not indicate the presence of targeted compounds at concentrations exceeding the MDLs for SM6200B or EPA‐504.1. The extent of surficial groundwater contamination has been nearly defined, with minor data gaps to the west and southeast of the source area. No free product was identified at the site during the June 2023 sampling event, nor has free product been identified during previous monitoring events. Based on groundwater elevation measurements obtained in June 2023, groundwater flow currently appears to be divergent to the southeast and northeast.  Gradient at the location may be affected by the removal of the USTs in December 2019 and emplacement of non‐native fill materials in the excavated area, in addition to groundwater averaging greater than 2.1‐ft shallower than that measured in June 2022. Analytical results for the samples obtained from water supply wells in June 2023 indicated the presence of 1,2‐DCE and EDB in WSW‐3A and WSW‐4 at concentrations in excess of their respective 2L Standards but beneath US EPA MCLs.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as- received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report.

The above referenced project has been analyzed per your instructions. The analyses were performed in accordance with the applicable analytical method. The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance. The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as- received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.

Your Success. Soil Sampling, Soil Boring and Monitor Well Installation, Well Development Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may be collected from drill cuttings associated with the boring or well installation. Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells). Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas where shallow groundwater is encountered, a variance to construction standards may be employed to ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at or above grade, and are abandoned within 24-hours of their installation. Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump, dependent upon site conditions. When wells are developed by the driller, they may be developed with any of the methods outlined above, in addition to air or water injection. Soil boring logs and well construction details are typically prepared for presentation in a report appendix. Borings completed in bedrock may be drilled using air rotary, coring, or sonic drilling methods. Groundwater Depth to Water Measurements Groundwater level measurements are typically obtained using an electronic water level indicator which registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot intervals into the well until the probe of the meter intersects the water surface. The measurement from the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The electronic water level indicator probe and exposed probe cable is decontaminated between measurement locations. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Free Product Level Measurements Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using an electronic oil/water interface probe. The interface probe has both an audible and illuminating light that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is decontaminated between measurement locations. Soil Sampling and Field Screening Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling procedures are followed to protect the chemical integrity of the soil samples and minimize the potential for cross contamination between sample locations, including discarding of the exterior of the sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling equipment, and the thorough decontamination of sampling apparatus prior to use and between sample locations. Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples from excavation equipment includes retrieving native soil from material that has not made contact with the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers as described above. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination or field personnel exposure to contaminants. Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or shovels, are decontaminated prior to their use in the collection of samples. Samples are placed within laboratory grade sample containers provided by the laboratory to which the samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other portable screening device. Screening of samples with a PID, FID or other field screening device is performed in accordance with device manufacturer specifications for screening, following calibration of the instrument based on manufacturer recommended procedures. Generalized Standard Operating Procedures (Not All Inclusive) WithersRavenel Our People. Your Success. Groundwater Sampling Groundwater samples are generally collected using one of three standard methods – through the use of a dedicated, disposable bailer, a peristaltic pump or submersible electric pump. When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to recover to within 80% of the original level measured prior to purging. When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is emplaced into the screened section of the monitoring well, and the pump is used to extract water through the tubing. When using the either of these methods, general water quality measurements including but not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific conductivity and turbidity may be used as methods for determining when an adequate purge of the well has been conducted. When water quality parameters are measured, the resulting data are included in well purge forms or field notes specific to each site and sampling point. Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater sample(s) are introduced directly into sample containers provided by the laboratory to which samples are ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre- preserved container(s) provided by the laboratory. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination of samples or field personnel exposure to contaminants. Water Supply Well Sampling Sampling of water supply wells is accomplished through the collection of a representative sample from an in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a point prior to any filtration or point of entry (POE) system which might be installed on a well. In some cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse. In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is contained in laboratory grade sample containers as described in the previous section. Water quality parameters may be (but are not necessarily) measured in association with the well purging. Supply wells without active power supplies are not generally sampled, as the well seal cannot be compromised by individuals not certified as a well contractor. However, in the case of a well with no power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or electric submersible pump.

Decontamination Procedures Decontamination procedures employed in the performance of field activities will vary dependent upon the method(s) of sampling performed at any site, but will generally include the following: • Remove excess soil/sludge from any sampling equipment as needed, • Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in a contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as necessary, • Rinse thoroughly with tap water, • Rinse thoroughly with analyte-free water (deionized water),  Rinse thoroughly with isopropyl alcohol, • Allow the equipment to air dry, • Prevent inadvertent contamination during storage and transport (accomplished through storage of equipment in foil or plastic bags/sheeting). In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may be decontaminated prior to their disposal. In general, no decontamination of these items is necessary prior to their use in sampling.
